Bio-Rad's disposable cuvettes are molded from polystyrene, making them ideal for use with the Bio-Rad protein assay, the DC protein assay, and the RC DC protein assay. The cuvettes adsorb less Coomassie blue dye than glass cuvettes and much less than quartz cuvettes. Assays can be mixed directly in the cuvette and the volume of reagents can be cut in half, yielding twice as many assays per kit.

Bio-Rad's standard disposable polystyrene cuvette holds up to 3.5 ml, allowing assays to be mixed directly in the cuvette. The 1.5 ml semimicrovolume disposable polystyrene cuvette is ideal for working with smaller volumes.

Both standard and semimicrovolume cuvettes are sized to fit most spectrophotometers. The cuvettes have smooth optical surfaces for consistent and accurate readings and the nonoptical walls are grooved for an easy grip and to provide orientation.

What is the education discount policy?

For more than 15 years, Bio-Rad has made science education a major priority. To support this effort, the company has implemented a discount policy that allows high school and college teaching laboratories to purchase kits, instruments, reagents, and other equipment at preferred prices.

How do I apply for the education discount?
